What Is Data Loss Prevention (DLP) Compliance?
Why Is DLP Compliance Important?
Organizations must protect personally identifiable information (PII) at all times, which includes a variety of sensitive data, such as name, address, phone number, email, banking and social security information, religion, and sexual orientation. It also includes social media profiles, IP addresses, and internet browsing history.
Data breaches must be prevented, and in the event of a violation, the company should immediately communicate with all affected parties and the regulating body. The CCPA and GDPR provide individuals with the right to access and request the deletion of their PII.
To comply with regulations, organizations must track PII storage and movements, apply access rules, and implement data protection measures using technology.
DLP Regulatory Compliance Explained
Data loss prevention (DLP) compliance involves adhering to the laws and regulations established by various jurisdictions to protect sensitive data from unauthorized access, misuse, and disclosure, whether at rest, in motion, or in use. Organizations are required to implement controls and technologies that monitor, identify, and prevent the inappropriate transfer or exposure of sensitive data within and outside their network boundaries, including cloud-based systems.
For the most part, DLP compliance focuses on safeguarding the following types of sensitive data:
- Personal Identifiable Information (PII): Data that can be used independently or with other information to identify, contact, or locate a single person.
- Protected Health Information (PHI): Information related to health status, provision of healthcare, or payment for healthcare linked to an individual.
- Financial Information: Cybercrimes often target credit card numbers, bank account details, and other financial data.
- Intellectual Property: Company-specific data such as trade secrets, patents, proprietary product information, etc.
DLP regulatory compliance is about having the right tools and ensuring policies and procedures align with legal requirements. Organizations must stay informed about relevant data protection laws, such as the General Data Protection Regulation (GDPR) in Europe, the Health Insurance Portability and Accountability Act (HIPAA) in the United States..
Noncompliance can lead to legal penalties, financial losses, and damage to an organization's reputation.
GDPR, HIPAA, and Other Key Regulations
Navigating the complex web of compliance standards is a daunting task. Each industry has specific regulations; understanding these is key to developing an effective DLP strategy.
The GDPR and HIPAA are two well known examples of regulations impacting DLP strategies. GDPR has global implications for data privacy, while HIPAA governs the confidentiality of health information in the U.S.
DLP compliance extends to the Payment Card Industry Data Security Standard. The PCI DSS’ set of security standards ensures that all organizations accepting, processing, storing, or transmitting credit card information maintain a secure environment. The PCI DSS, aiming to protect against credit card fraud through increased controls around data and its exposure to compromise, is mandated by major credit card organizations.
Types of Data Threats
Data loss poses a significant threat to an organization's sensitive information and its operational stability. DLP must address a spectrum of data loss risks, including:
- Unintentional actions like accidental employee deletion or modification
- Technical failures like hardware malfunctions and software corruption
- Natural disasters impacting physical data storage
The data security challenges organizations confront underscores the importance of effective DLP strategies. These strategies are essential for mitigating data threats, ensuring data integrity, and maintaining compliance with various regulatory standards.
Insider Threats
Insider threats are among organizations' most significant and challenging data threats. DLP systems help prevent unauthorized access, copying, or destruction of sensitive data by insiders, including employees, ex-employees, contractors, and vendors. These insiders can leak, destroy, or steal sensitive data, harming the organization's reputation, financial stability, and data integrity.
External Attacks
External attacks often involve attempts to exfiltrate data, which can be achieved through phishing or malware-based attacks. DLP systems help prevent data loss or destruction during ransomware attacks, which can devastate an organization's operations and reputation.
Accidental Data Exposure
Accidental data exposure systems effectively detect and prevent exposure incidents like an employee inadvertently sending sensitive information to an external party. This type of data exposure can be a significant risk to an organization's data integrity and regulatory compliance.
Regulatory Violations
Regulatory violations can lead to severe penalties and reputational damage. DLP helps organizations comply with data regulatory frameworks such as GDPR by monitoring and controlling data, reducing the risk of violations.
Data Exfiltration and Breaches
Data exfiltration and breaches are among the most severe data threats, often resulting in significant financial losses and reputational damage. DLP solutions help monitor and prevent data leaks, which can occur through phishing or DDoS attacks.
Negligence
Negligence is a data threat that can lead to data breaches. DLP can provide comprehensive training and monitoring to mitigate these risks. By implementing rigorous security procedures and cybersecurity training, organizations can reduce the risk of data breaches due to negligence.
DLP Solutions
DLP solutions are essential for protecting intellectual property and PII, safeguarding critical data like trade secrets and PII, which are vital for an organization's integrity and compliance.
How Does DLP Work?
Data loss prevention protects sensitive or critical information from being lost or leaked by identifying information based on criteria, such as credit card numbers, or by customizing the system to include types of corporate data.
Assessing Risks and Data Vulnerabilities
The first step in DLP is identifying what constitutes sensitive data. This varies by industry and regulatory framework but generally includes personal identification numbers, financial information, health records, and intellectual property. Conducting a thorough risk assessment helps pinpoint data storage, transmission, and access vulnerabilities.
Continuous Monitoring
DLP tools continuously monitor data on endpoints, network traffic, and storage to detect potential data breaches or policy violations. Organizations set policies that define how different types of data can be handled, and DLP tools enforce these policies to control what users can do with the data.
Alerts and Reports
In case of policy violations or suspicious activities, DLP systems alert administrators and can take predefined actions, such as blocking data transfers. They also generate reports for compliance and auditing purposes. DLP solutions often integrate with other security systems, such as encryption, to offer layered protection to data. A multifaceted approach fortifies security against data loss or leakage.
Three main types of data loss prevention solutions:
Endpoint DLP
Endpoint data loss prevention solutions monitor endpoint devices, such as servers, computers, laptops, and mobile devices where data is stored and accessed. Endpoint DLP solutions can protect data from loss or theft by:
- Implementing real-time monitoring and protection of sensitive data on endpoint devices, including desktops, laptops, and mobile devices
- Enforcing policy-driven identification and classification of sensitive data stored or processed on endpoint devices
- Controlling data access, sharing, and transfer from endpoints, both on and off the corporate network
- Integrating endpoint DLP solutions with existing network and cloud data protection infrastructure
- Monitoring and logging user activity on endpoints to detect potential data loss events and maintain compliance
- Automating incident response and remediation workflows for potential data breaches originating from endpoints
- Encrypting sensitive data on endpoint devices to ensure secure storage and compliance with data protection regulations
